CORSAIR XMS does't work any more:-(

[fighter]

My MSI RS482M4-ILD Socket 939 ATI Radeon Xpress 200 worked well with

CORSAIR XMS 1GB (2 x 512MB) DDR 400 over one year. 4 months ago I bought extra 1GB (2 x 512MB) and successfully installed it. All settings in BIOS set by default. I had no issues for 3 months; yesterday I was not able to boot my WinXP. Computer reloads in infinitive loop. When I removed newer 1GB out of MB everything works fine again. As soon as I add it back to MB, computer reloads and reloads. Do I have to send RAM back to Corsair for replacement?

Welcome to the forums, fighter!

 

There could be several problems for this.

 

First off, what CPU do you have? There's an issue with running 4 double-sided DIMM's with certain AMD 64 processors.

 

Also, what DDR voltage are you running these modules at? It should be about 2.8 or 2.9 volts (do not exceed 2.9) for this setup. A 'chronic' case of low-voltage may slowly damage parts.

 

What power supply and other goodies are in your computer as well?

 

And finally, try JUST THE NEW PAIR ALONE and test with Memtest86+ to see if they're failing.

I am using AMD Athlon 64 3200+ Venice 2.0GHz. Voltaget set in AUTO mode, I did not set it manually. 550w power supply, 1 DVD drive and 2 SATA 350Gb HDs. As I said before, everything worked well for 3-4 months

This does not rule out the possibility of an IC conflict. If you are mixing 2 different types/brands of ICs when you mix the memory, this can result in instability. Can you please post all of the information from your MEMORY LABELs for all 4 DIMMs.

 

Can you also list the specification and brand name for your PSU?

First of all thank you for FAST reply and support.

this one works great:

CMX512-3200C2PT

XMS3202V5.2

lot number: 0546121-0

XMS3200 512MB 400Mhz CL2

 

this one worked well for 3 months and now rebooting my comp

CMX512-3200C2PT

XMS3202V5.2

lot number: 0626220-0

XMS3200 512MB 400Mhz CL2

 

My PSU is Antec Neo HE 550wt

 

P.S. Burned CD with Memtest86+. It shows lots of errors for lot number: 0626220-0

P.P.S. Memtest86+ shows errors just for one DIMM from lot number: 0626220-0. Second one passed test successfully.

If you have a DIMM failing Memtest, let's get that pair of modules replaced. Please use the link in my signature below for "I Think I Have a Bad Part".

 

Keep in mind that you are mixing ICs when use 2 different lots or rev's of memory together.

I will open RMA request today, thank you for support. AMAZING service, I would recommend corsair memory to all my friends!!!
